Can a person still have a heart attack after a stent?

"If a person has a stent, they are still at risk of having a heart attack or stroke," US government's NIH said. This happens if underlying risk factors like high cholesterol and high blood pressure aren't managed. "Stent...clears a traffic jam in one specific artery, but it doesn't cure underlying disease," Dr Subhash Chandra of Max Super Speciality Hospital said.
